Much has been made of Mark Twain’s finanÂcial problems—the impruÂdent investÂments and poor manÂageÂment skills that forced him to shutÂter his large HartÂford estate and move his famÂiÂly to Europe in 1891. An earÂly adopter of the typeÂwriter and long an enthuÂsiÂast of new sciÂence and techÂnolÂoÂgy, Twain lost the bulk of his forÂtune by investÂing huge sums—roughly eight milÂlion dolÂlars total in today’s money—on a typeÂsetÂting machine, buyÂing the rights to the appaÂraÂtus outÂright in 1889. The venÂture bankÂruptÂed him. The machine was overÂcomÂpliÂcatÂed and freÂquentÂly broke down, and “before it could be made to work conÂsisÂtentÂly,” writes the UniÂverÂsiÂty of Virginia’s Mark Twain library, “the LinoÂtype machine swept the marÂket [Twain] had hoped to corÂner.”
Twain’s seemÂingÂly blind enthuÂsiÂasm for the ill-fatÂed machine makes him seem like a bunÂgler in pracÂtiÂcal matÂters. But that impresÂsion should be temÂpered by the acknowlÂedgeÂment that Twain was not only an enthuÂsiÂast of techÂnolÂoÂgy, but also a canÂny invenÂtor who patentÂed a few techÂnoloÂgies, one of which is still highÂly in use today and, indeed, shows no signs of going anyÂwhere. I refer to the ubiqÂuiÂtous elasÂtic hook clasp at the back of nearÂly every bra, an invenÂtion Twain patentÂed in 1871 under his givÂen name Samuel L. Clemens. (View the origÂiÂnal patent here.) You can see the diaÂgram for his invenÂtion above. CallÂing it an “ImproveÂment in Adjustable and DetachÂable Straps for GarÂments,” Twain made no menÂtion of ladies’ underÂgarÂments in his patent appliÂcaÂtion, referÂring instead to “the vest, panÂtaloons, or othÂer garÂment upon which my strap is to be used.”

The device, writes the US Patent and TradeÂmark Office, “was not only used for shirts, but underÂpants and women’s corsets as well. His purÂpose was to do away with susÂpenders, which he conÂsidÂered uncomÂfortÂable.” (At the time, belts served a mostÂly decÂoÂraÂtive funcÂtion.) Twain’s invenÂtions tendÂed to solve probÂlems he encounÂtered in his daiÂly life, and his next patent was for a hobÂbyÂist set of which he himÂself was a memÂber. After the soon-to-be bra strap, Twain devised a method of improveÂment in scrapÂbookÂing, an avid purÂsuit of his, in 1873.
PreÂviÂousÂly, scrapÂbooks were assemÂbled by hand-gluÂing each item, which Twain seemed to conÂsidÂer an overÂly laboÂriÂous and messy process. His invenÂtion—writes The Atlantic in part of a series they call “Patents of the Rich and Famous”—involved “two posÂsiÂble self-adheÂsive sysÂtems,” simÂiÂlar to self-sealÂing envelopes, in which, as his patent states, “the surÂfaces of the leaves whereÂof are coatÂed with a suitÂable adheÂsive subÂstance covÂerÂing the whole or parts of the entire surÂface.” (See the less-than-clear diaÂgram for the invenÂtion above.) The scrapÂbookÂing device proved “very popÂuÂlar,” writes the US Patent Office, “and sold over 25,000 copies.”

Twain obtained his final patent in 1885 for a “Game AppaÂraÂtus” that he called the “MemÂoÂry-Builder” (see it above). The object of the game was priÂmarÂiÂly eduÂcaÂtionÂal, helpÂing, as he wrote, to “fill the children’s heads with dates withÂout study.” As we reportÂed in a preÂviÂous post, “Twain worked out a way to play it on a cribÂbage board conÂvertÂed into a hisÂtorÂiÂcal timeÂline.” Unlike his first two invenÂtions, the game met with no comÂmerÂcial sucÂcess. “Twain sent a few proÂtoÂtypes to toy stores in 1891,” writes RebecÂca Onion at Slate, “but there wasn’t very much interÂest, so the game nevÂer went into proÂducÂtion.” NonetheÂless, we still have Twain to thank, or to damn, for the bra strap, an invenÂtion of no small imporÂtance.
Twain himÂself seems to have had some conÂtraÂdicÂtoÂry attiÂtudes about his role as an invenÂtor, and of the sinÂguÂlar recogÂniÂtion grantÂed to indiÂvidÂuÂals through patent law. PerÂhaps unsurÂprisÂingÂly, the US Patent Office claims that Twain “believed strongÂly in the valÂue of the patent sysÂtem” and cites a pasÂsage from A ConÂnectiÂcut YanÂkee in King Arthur’s Court in supÂport. But in a letÂter Twain wrote to Helen Keller in 1903, he expressed a very difÂferÂent view. “It takes a thouÂsand men to invent a teleÂgraph, or a steam engine, or a phonoÂgraph, or a teleÂphone or any othÂer imporÂtant thing,” Twain wrote, “and the last man gets the credÂit and we forÂget the othÂers. He added his litÂtle mite—that is all he did. These object lessons should teach us that nineÂty-nine parts of all things that proÂceed from the intelÂlect are plaÂgiaÂrisms, pure and simÂple.”
